I've been trying to install a pace edwards powergate on my truck. I have to tap into my lock/unlock wires inside my door panel. The install intructions show a 5 wire harness with 2 tan wires, a purple, yellow, and orange i believe. A chevy tech told me that it should only be 4 wires coming from the switch and they should be yellow, tan, purple and green. The colors coming from my switch are pink, orange, black, and brown. Does anyone own a 2010 silverado 1500 and know which wire harness to use?
